A quarterback throws a pass at an angle of 40 degrees above the horizontal with an initial speed of 20 m/s. The ball is caught by the receiver 2.55 seconds later. Determine horizontal velocity, vertical initial velocity, the distance ball was thrown, and maximum height of the ball?

Answer 1

well, the vertical position at time t is

y(t) = 20 sin40° t - 4.9t^2
= 12.86t - 4.9t^2

I think that should get you started ok.
